摘要
以大连国际会议中心为工程背景,应用大型通用有限元分析软件ANSYS对内置加劲环空间圆管相贯节点进行了非线性有限元分析.本文简要介绍了计算节点有限元模型各关键参数的具体设置,系统分析了在其他参数不变的前提下内加劲环间距对节点强度、刚度以及破坏模式等性能的影响,提出了在相贯节点主管内设置加劲环的合理构造要求,为该工程的设计提供了理论依据.
Based on Dalian international conference center project,the behavior of multiplanar circular hollow section joints with internal stiffeners is studied by ANSYS.Parameters in model is briefly introduced.and effect of stiffener spaceing on strength,stiffness and damage model of the joint is investigted on the premise of invariability of other parameters.Some reasonable detailing requirements of internal stiffeners are proposed which provides theoretical basis for designes of this project.
